Your Pulse Oximeter

Posted by admin in Health writer on 10 3rd, 2009 | one response

Pulse oximetry has gained wide spread clinical acceptance in the latter part of the 21st century. This is in part due to the development of the microprocessor, better patient sensor design, and better data processing algorithms. Virtually every patient, whether in the hospital, subacute care center or at home, that has oxygen or mechanical ventilation requirements would benefit from pulse oximetry. This may be in the form of continuous monitoring or intermittent diagnostic testing.

Clinical Environments and Applications of Pulse Oximetry

Anesthesia
In OR/General Anesthesia
Monitoring Care During Conscious Sedation
PACU
Intensive Care Units
Neonatal
Intensive Care
Newborn Nursery
Delivery Suites
Transport
Internal (within the Hospital)
External
Ambulance/Air Transport
Diagnostic Lab
PFT Lab
Exercise Lab
Sleep Lab
Subacute Care Centers
Home Care Patients
Other Patient Conditions
Blood Flow Assessment
Cardiopulmonary Arrest
Asthma
Seisures
In Conjunction with Other Modalities
Dual Oximetry (SpO2 and SvO2)
Others

Assessing the results. A normal reading, for a person breathing room air, is in the high 90s. A reading of anywhere from 96% SpO2 through 99% SpO2 is typically not cause for alarm. A reading of 95% SpO2 or less could indicate hypoxia and should be investigated. An SpO2 reading of 90% or less indicates significant hypoxia and requires immediate action.
Your pulse oximeter will also record your heart rate. Normal heart rates are as follows, depicted in beats per minute (bpm):

Elderly Person (75+): Normal - 90
Adult: Normal - 60-80 / Rapid - 100+ / Slow - below 60
Adolescent: Normal - 60-105 / Rapid - 105+ / Slow - below 50
Child (5-12 years): Normal - 60-120 / Rapid - 120+ / Slow - below 60
Child (1-5 years): Normal - 80-150 / Rapid - 150+ / Slow below 80
Infant: Normal - 120-150 / Rapid - 150+ / Slow - below 120
